HMD Wake-Up via Head Gesture and Eye Direction

The patent replaces traditional mechanical or manual wake-up interfaces (buttons, switches) with an optical-based eye-tracking system. The HMD uses cameras and light sources to detect eye position and head gestures, substituting physical interaction mechanisms with optical sensing to achieve more intuitive operation.

The system enables the HMD to automatically detect and respond to user intent through eye direction and head gesture recognition. The device serves itself by interpreting natural user behavior patterns without requiring explicit commands or complex interface interactions, making the wake-up process seamless and intuitive.

The patent combines multiple sensing functions (eye position detection, head gesture recognition, wake-up determination) into an integrated system. The camera module and light sources work together as a unified eye-tracking system, and the processor integrates data from both eye position and head movement sensors to make coordinated wake-up decisions, reducing overall system complexity through functional merging.

The camera and light source components serve multiple functions: they detect eye position for wake-up, track head gestures for interaction, and can potentially be used for other AR/VR applications. This multi-functionality justifies the sensor inclusion while maximizing their utility across different operational contexts.
